ETHELYN E. COLE, OF BENTON, WASHINGTON.

FLOUR SIFTER.

Application filed June 22, 1923.

To all whom it may concern:

Be it known that 1 ETHELYN E. COLE, a citizen of the United States,residing at Benton, in the county of King and Stateof \Vashington, haveinvented new and useful Improvements in Flour Sifters, of which thefollowing is a specification.

This invention relates to kitchen apparatus, particularly to sitters,and has for its object the provision of a novel sifter for mixing andsifting the flour and other dry ingredients used in baking.

An important object is the provision of a sifter of this character inwhich the sifting action is accomplished merely by shaking the deviceback and forth in the hand,

rubbers being provided upon each side of the sifting screen.

Another object is the provision of a device of this character which hasits body portion provided with detachable caps or cups which will enablethe dry ingredients to be run through the device repeatedly without itbeing necessary to deposit the ingredients in an auxiliary receptacle,the device in this way effecting a great saving in time, labor andmaterials.

An additional object is the provision of a sifter of this characterwhich will be simple and inexpensive in manufacture, highly efficient inuse, durable in service and a general improvement in the art.

With the above and other objects and advantages in view the inventionconsists in th details of construction to be hereinafter more fullydescribed and claimed and illustrated in the accompanying drawings, inwhich:

Figure l is a side elevation of the complete device,

Figure 2 is a longitudinal section therethrough,

Figure 3 is a cross section,

Figure 4 is a detail perspective view of the pivoting bracket,

Figure 5 is an enlarged detail section showing the slidable closureplate,

Figure 6 is a detail elevation looking toward the sliding plate,

Figure 7 is a detail view illustrating the manner of formation of theguides for the sliding plate,

Figure 8 is a detail section showing the cover holding means and Figure9 is a detail section showing the Serial No. 647,120.

manner of holding the screen within the shell or casing.

eferring more particularly to the drawings the numeral 10 designates thecylin drical body of the device which may be constructed of tin as iscustomary or any other suitable sheet material. The top of thisreceptacle is designed to be closed by a removable cap 11 held in placeby means of a co-acting projection and groove 12 and 13 constituting aspecies of bayonet slot connection. The lower end of the body ispreferably slightly reduced as indicated at 14 for engagement within theopen end of a detachable cup 15 likewise held in place by a projection16 and co-acrting groove 17. This cup 15 is formed with a series ofridges or grooves 18 which designate graduations so that the volume offlour or other dry material within the cup may be ascertained.

Located within the body is a sieve or screen 19 of suitable finenesshaving its edge bound with a metal binding 20 held within a slit groove21 in the body. The binding might be omitted but it adds stiffness tothe screen and is therefore preferably employed. Secured within the bodyagainst the inner wall thereof is a Ushaped bracket 22 riveted,soldered, or otherwise held in place, while at a diametrically oppositepoint the material of the body is slit as indicated at 23 and 24 and theedges of the slit are turned in and subsequently rebent to provide guideflanges 25 located at opposite sides of the resultant opening 26.

In connection wit-h the screen I provide a rubber structure formedpreferably from a single length of wire twisted together at 27intermediate its ends to define a handle 28 and two arms 29 located atopposite sides of the screen. The arm port-ions 29 are bent intoserpentine shape as indicated in the cross sectional view to provide arelatively large effective rubbing surface, or to provide long lines ofcontact of the arms with the screen. The free ends of the arms are bentin opposite directions and rebent as indicated at 30 with theirterminals 31 pivoted within suitable holes in the arms of the bracket22. Adjacent the twisted portion 27, the arms 29 pass through a curvedplate 82 which is slidable between the guide flanges 25 and which is ofconsiderably greater length than the opening 26 so as to cover thisopening at all times and prevent flour r other material from leaking outwhenthe device is in use. The device is used by pouring the flour ontothe sieve and shaking the device back and forth while holding itby thehandle 28'. The rubber arms 29 rubbing against the sieve will eiiectually break up any lumps of flour or other dry ingredients and alsocommingle them properly. This is the ordinary uSe but the deviceisparticu-larly well adapted for the more important operation oi notonly breaking up the lumpsbut mixing together the ingredients inthose-instances where repeated sifting is necessary. In this case thecup 15- is' engaged uponthe bot-y, the dry materials are placed withinthe device, and engaging the cap 11 in place. When the device is thenheld upright and shaken all the material will be broken up and mixed bybeing torced through the screen. All the material will then be in thecup 15. The dev ce is then turned over and the operation repeated whichwillv bring all the materialagain through the screen untilit accumulateswithin the cap 11., after which inversion is then accomplished and theoperation repeated in this way as many times as the recipe may call for.The advantage is that there is a great saving 0%? time and labor as wellas in material as there is nothing lost by placing the material in anyauxiliary receptacle. 7 From the foregoing description and a study ofthe drawings it will be apparent that I have thus provided a simplyconstructed and inexpensive sitter which will be highly efficient forall the purposes specified and which on account of its simplicity is notlikelyto get out of order at any time,- ample provision is made forpreventing leaking or loss of material from any source.

While I have shown and described the preferred embodiment of theinvention it is of course to be understood that I reserve the right tomake such changes in the form, construction and arrangement of parts aswill not depart from thespirit of the invention or the scope of thesubjoined claims.

Having thus described my invention 1 claim;

1. In a flour sitter, a hollow body, a screen secured within andextending across the intermediate portion thereof, a U- shaped bracketsecured against the inside of the wall and straddling said screen, thebody being formed with an elongated lateral slot opposite said bracket,channeled gnides formed integrally with the body at the longitudinaledges of said slot, a curved plate slidable along said guides, and arubbing member formed from a single length of wire and inchidling armsextending through said plate and arranged at opposite sides of thescreen, each arm having its intermediate portion of serpentine tormationand terminating at its inner end in a hook, said hooks being oppositelyarranged, directed toward the screen and pivotally engaged with the armsof said bracket.

2. A flour sitter comprising an elongated hollow cylindrical body,receptacles detachabl'y connected with the ends 01 the body, screenwithin the body, a pair oi? rubbing arms pivoted at one end within thebody and located at opposite sides of the screen, said arms having theirscreen engaging pmti-ons termed serpentine, said body being formed withan elongated slot pern-iittinnlateral movement of the rubbing arms, anda plate carried by the arms and always covering said slot, said armsbeing both formed from a singlelength of wire having; its intermediateportion twisted to form a bandle and having its ends terminating inpivot extensions, and a bracket located within the body and with whichsaid pivot ends are: engaged.

In testimony whereof I allix my signature.
